Method and access device for implementing IP broadband video service

摘要

Embodiments of the present invention disclose a method and an access device for implementing an IP broadband video service, the method is executed by an access device, includes: receiving a request for demanding a program from the user terminal; checking a right of a user corresponding to the user terminal; if the user has right to demand the program and is the first member joining the program group, sending the request to the multicast router and then sending the user terminal a multicast stream of the program received from the multicast router; if the user has right to demand the program and is not the first member joining the group, sending the multicast stream to the user terminal; the method further comprises: generating a record comprising program information and time information that indicates program join and leave activities and sending the record to a video service support system.

主权项

1. A method for implementing an Internet Protocol (IP) broadband video service, comprising:
receiving, from a user terminal by an access device located between the user terminal and a multicast router, a request for demanding a program; checking, by the access device upon receiving the request, at least one right of a user corresponding to the user terminal; when the at least one right corresponding to the user terminal includes a right to demand the program and the user is a first member joining a multicast group that corresponds to the program, performing, by the access device:
recording a time for the user terminal joining the multicast group,sending the request for the program to a multicast router,receiving a multicast stream of the program on demand from the multicast router,sending the multicast stream of the program to the user terminal,recording a time for the user terminal leaving the multicast group, andsending a record including the time for the user terminal joining the multicast group and the time for the user terminal leaving the multicast group to a video service support system; and when the at least one right of a user corresponding to the user terminal includes a right to demand the program and the user is not the first member joining the multicast group that corresponds to the program, performing, by the access device: recording a time for the user terminal joining the multicast group while sending the multicast stream of the program to the user terminal; recording a time for the user terminal leaving the multicast group, and sending a record including the time for the user terminal joining the multicast group and the time for the user terminal leaving the multicast group to a video service support system.
